MAX rHE'IM R, or ELIZABETH, NEW JERSEY.

To all whom it concern: Be it known that 1, MAX THEIMER, a citizeirof-the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented new and useful. Improvements in Bone-Holding Devices.

My'inventionconsists of a device suitably constructed to assist in rigidly holding a bone during the operation of sawing said bone. Hitherto'such devices have been of a construction in general resembling a bench vise. But owing to the inherent irregularities in the shapes of bones, the comparatively large bearingareas of the jaws of such vises do not properly grip the bones. In ad- 1' dition to this, said vises' are bulky, and be-. ing rigidly fixed. to 'the butch'ers block or {j Tothe rtable are in hisway when performing operations other than bone-sawing. An important feature of mydevice is the use-of a comparatively thin plate suitably notched to receive the bone, aifording a knife edge grip. which is not weakened-by irregulari ties in the shape of the bone. Furthermore the sides of the notch are serrated, being furnished with sharpteeth ingeneral, having. their axes pointing downward. This greatly lassists'in holding down the bone in the notch and-preventing its rotation, it be ingunderstood that one end of the bone held by the operator,-: while the other end rests in thenotchp A. further feature of my invention is that the notched plate is suit- .ably mounted to permitiof its being easily moved into inoperative position, out of the 7 way of the'butch'er when its use is not re -quired'." Owing'to its fiat shape and small size, my bone holding deviceis very compact in its inoperative position, affording a, minimum of interferencewith thelmoveme'nts of an operator'about the table. The other features of this device will be made evident from the detailed description.

' Reference is. to drawings illustrating-my device, in whic Figure 1 is a front elevation of my preferred form, with the device in operative po-f sition.

Figs. 10 and 11 are views respectively of operative and inoperative positions of an alternative form of myinvention in which the notched-plate is detachable.

Referring now to Figs. 1, 2, 3, 4L and 5, the

bracket 1 is provided with holes through which screws 2 can be passed for fastening j the bracket to the meat block, The upper. portion of bracket 1 is bent over'toform the guides 3, and the lower'portion is bent over to for nthe guides 4. The upper and lower portions of guides 4 are bent to substantially horizontal planes as shown in Fig/Qin order to limit the motion of plate 5. The curved V shaped notch 9 of plate 5 is provided, preferably with acute-angled teeth 10. The

sides of plate 5. are provided with indenta tions with outer portions 6 which are adapt ed to fit over the outside. of guides 3 (Figs. 1 and 3) and innercurved portions 7 which fit within guides 3 when plate 5 is in its operative, position. The rounding of portion 7 facilitates its entrance into the guides 3.

Integral with the lower end of plate 5 4) are lugs 8, which are adapted to play within-the guides 4. v

In operation, the plate 5 is in the erect position shown in Fig. 1. Thebutcher can now insert the bone into the curve V shaped notch 9. It is preferableto'insert the heavier end ofthe bone" into the notch holding the lighter end in one hand and wielding the bone-saw with the other. The sides of the V notch are made curved. to more nearly conform to the shapeof theaverage bone.

When the butcher is through using the device. inorder to move plate 5 into its inoperative position', he first lifts it into the dotted position shown in Fi'g. 1 in order to clear the portions 6. and 7 of the guides Then he swings plate 5 outwardlv piyoting upon the lugs 8, and releases it.
